[Circle Launches Agent Stack Toolkit, Enabling AI Agents to Independently Utilize USDC Funds] According to Decrypt, USDC issuer Circle has launched the Agent Stack toolkit, allowing AI agents to independently hold funds, pay fees, and conduct transactions using USDC without human intervention. Core products include agent wallets, a command-line interface, an agent marketplace, and a nano payment protocol that supports micro-transfers as small as $0.000001 without gas fees. Circle stated that traditional financial systems are designed for humans, making it impossible for AI agents to operate autonomously, thus requiring a reconstruction of the infrastructure. Circle co-founder Jeremy Allaire described Agent Stack as the first financial service suite that treats AI agents themselves as customers.
